Bertrand, can you share `lspci -t` output, and also `lspci -vvs 80:00.0` ?
I don't have any device at address 80:00.0.
Oh, that's why it fails...
This feels like a firmware (if not hardware) issue, I think root complex should be visible normally... But maybe somebody more familiar with PCIe spec can help?
Yeah, checking if there is any firmware update available would be a good idea, as to me it is a bit odd to see the separate hierarchy without a host bridge at 0000:80:00.0. Admittedly I'm not a PCIE expert though
